I own a MacBook Pro, Mid 2014, and its 256 SSD started facing problems almost 8 months after I bought it. I've been looking to replace it.
I've read over at iFixit that you can replace it,
But as I understand that not every SSD is compatible. So I was wondering whether this Samsung 850 Pro 256GB 2.5-Inch SATA III Internal SSD would be compatible?
It turned out that the hard drive cable was broken. Replacing it fixed the problem completely.
You probably have one of the following enabled that could explain the power drain.
Power Nap or Wake on WiFi, disable them,
or read the small print that says what it will do in sleep :)
Also as said earlier, open the Console and type "Wake" in the search window of the Console.
Now look who and what is waking it up and what is it for what reason and what is it doing about it.
As for your question why is it consuming more power, well you added more lights to the Christmas tree.
For example when HDD sleeps it does not consumes any power. The cussing SSD does consume power since it reshuffle it self from time to time, that is normal for SSD to refresh its memory cells.
UPDATE:
according to apple, you computer does not support the Power Nap mode settings thus enable/disable activity during the sleep.
So back to the Console reports:
Type "Wake" and look what is waking it up or keeping it awake based on time stamps.
Going on a limb, I would say it is your Trim support for the SSD, that you will find in the Console.
The TRIM command is an important disk command for SSDs that keeps your flash memory appropriately cycled so that you can achieve faster read and write speeds, as well as a longer lifespan for your SSD.

No, that SSD is not compatible with your MacBook Pro, as the form factor is different. Your Mac takes "blade" SSD, while the one on Amazon is the regular old hard drive-like enclosure. Personally, I recommend Intel for SSDs, I've had great luck with them.
